Subject: [PATCH 3/6] vhost_test: remove vhost_test_flush_vq()

vhost_test_flush_vq() just a simple wrapper around vhost_work_dev_flush()
which seems have no value. It's just easier to call vhost_work_dev_flush()
directly. Besides there is no point in obtaining vhost_dev pointer
via 'n->vqs[index].poll.dev' while we can just use &n->dev.
It's the same pointers, see vhost_test_open()/vhost_dev_init().
